An ERV helps reduce this effect because not all moisture is removed from the building with the exhaust air.<\/p>\n<h2 data-section-id=\"1vol86f\" data-start=\"7896\" data-end=\"7922\">AirOne ERV for the bedroom<\/h2>\n<p data-start=\"7924\" data-end=\"8017\">The bedroom is one of the rooms where local ERV ventilation can be particularly beneficial.<\/p>\n<p data-start=\"8019\" data-end=\"8192\">During the night, people produce <strong data-start=\"8051\" data-end=\"8074\">both CO\u2082 and moisture<\/strong>. Ventilation must remove the CO\u2082, but in very cold weather, high air exchange rates can simultaneously make the room too dry.<\/p>\n<p data-start=\"8194\" data-end=\"8261\">An ERV heat exchanger
